A choice, sharp old Rosiclaire, Illinois Fluorite dusted with a little sparkling Quartz. Very good translucency, this backlights very well and shows multiple internal colors. In sunlight or daylight balanced light sources this is a nice blue with hints of yellow and some red internal color. Incandescent lighting turns this a more purple color. Overall in very good condition, a close exam finds some very tiny edge bruises but these are clearly not distracting yet keep the price low. Better in person, strong display and now getting very hard to find this quality at reasonable costs.
